Zerby Derby


Bob the Boat finds a new part of Zerby Town Lake to explore. But there are a lot of rocks just under the water that Bob can't see and he keeps running up on them. Bob calls Zack and Fran the Ferry to help. They suggest that Bob could try to remember where all the rocks are, but there are too many to remember. Strut tries clearing some out, but it would take all day to clear them all. Finally they realize that if Bob marks the rocks with sticks then it makes it really easy to know where all the rocks are.
